Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater

1 Answer

Honeywell visionpro My Vision Pro 8000 thermostat won't turn off my boiler, regardless of the temperature, or even if it's in heating or cooling mode. I actually have a second (identical) stat in the house, and I installed it on the same face plate, and the boiler went back to normal operation. Is there a way to reset or re-boot the thing? I already changed the batteries, and Honeywell said it's a bad unit. Weird problem.

SOURCE: Honeywell TH8320u Vision Pro 8000 Digital keeps calling for heat

Hi,
If the thermostat is not over shooting the temperature than don't worry about it.
These thermostats are very sensitive and will turn the heat back on even before the degrees drop on the display. Often they will shut down before the display changes also. You can change the sensitivity of the thermpstat if you read the directions and change the cycles per hour to a less number. There is an installers program in there that you need to push a combiunation of buttons to get too. The instructions tell you how to do that also.

Hopefully you did not throw away the instruction manual for your t-stat.. :-)

Even when system is turned off the fan runs. put batteries in as there were none, no change. is thermostat shot?this an ac/furnace unit with vision pro th8000 series thermostat


The issue is probably not the thermostat. The thermostat is a series of switches that turn on and off in respect to the temperature. Since it takes batteries and installing those made no difference there is a chance that a relay is stuck in the furnace or the thermostat. I have attached the testing and installation guide for you to look at. Honeywell VisionPRO TH8000 Series Installation Manual Installer System Test

Heat element light comes on (so there is power) but the iron will not hear up


The Delonghi Pro300 has two thermostats that contact the boiler. One is a low temperature thermostat that allows the boiler to heat up to 145 degrees (F). The other turns off the boiler when the temperature reaches 180 degrees. It sounds like your low temperature thermostat has failed. The part can be ordered on line. You need to have good basic mechanical skills and the proper sized star screwdriver to replace it.

Will a th5000 work with a ruud dual fuel


Are you talking about a pro 5000 Thermostat??? if so then NO it will not work.With this stat you do not have a temperature lock on the heat pump. Say you don't want the heat pump to run below 25 degrees. it won't shut the heat pump. And you don't want the heat pump to run at the same time as the furnace. With the Pro 8000 3 heat and 2 cool thermostat you can lock out the heat pump at 25 degrees outside an turn the furnace on. You will have to install an outdoor thermostat hooked up to the pro 8000 it usually comes with the stat. Honeywell products.

Not sure which 8000 you have but it looks like all of them have the auto changeover option. Press system, you should see "heat/cool/auto/off" this is the auto changeover. So system is on auto, fan should be on auto. Send model number if you can't get it!

Why won't my lg ductless heat pump regulate the room temperature?


After I have been reading up on your unit it appears that the thermostat is not operating correctly. I found this real basic information on installation for your unit. This link I am giving is pretty basic instal schematics. But seems to be something about your thermostat needs to be dialed in or is not working properly.

Set back thermostat has mind of its own.


The Honeywell Vision Pro 8000 can be complicated to figure out if it isn't set up right from the system menu. There are so many things that you can make it do, sometimes the most common things are wrong. My question is ''what kind of system do you have, heat pump or not?, and is the system gas or oil?" If I knew these things, I could definitely help you figure out if the thermostat is set up right. I have the manual so that I can give you exact numbers. Just in case, you can email me at : kingbrizzle@aim.com
